your forgetting tht Naruto can touch Tobi aslong as he is in kyubi modeI honestly think tobi is, hes got izanagi and he can pass through solid matter. Unless ofcourse you stretch it like konan for like 10 minutes which naruto propably can do with enough nine tails power but I think she was pretty strong aswell. I dont see how naruto can win unless the nine tails has some jutsu that no other jutsu works against. How can one win against one who can twist reality?
If your referring to tobis comment "I shouldv slipped through you but you couldnt even scratch my mask?" this could mean that he wanted to slip through him but naruto was too quick, or that he cant slip through him as you said. Im going off the assumption that he can slip through him because comments like that are sometimes two sided.your forgetting tht Naruto can touch Tobi aslong as he is in kyubi mode
